"t3 t4 is normal"
The normal ranges are to be taken lightly. Its not a light switch like on or off.
People at the low end of normal T values can naturally feel hypo and vise versa.
TSH on the other hand, is not as important but unfortunately MDs use this more. And insurance like it cause its one test and cheaper cost. That said, your TSH does support being hypo.
So take that info in addition to what others said about symptomatic feel, and that is your answer. We cant tell you any more without knowing your symptoms or T3 and T4 values with their ranges.
Yes, how you feel is key.
Uncomfortable? In pain? Limited or restricted from doing things you need or want to do?
Do you happen to have the results with the reference ranges? Also, how do you feel?
